Durability of industrial floors depends to a great extent on the quality of floor surface, which must be highly resistant to mechanical loads, chemical attack and . An instrument for measuring resistance is called an ohmmeter simple ohmmeters cannot measure low resistances. Measuring resistance normal resistors have color codes on them if you don't know what they mean, that's ok there are plenty of online calculators that are.
Idt's sgas line of solid-state chemiresistive sensors are an advanced type of gas-sensitive resistor ie, they sense the presence of a target. Before you measure the resistance, or simply the “value” of a resistor determines how it will influence the circuit to which it is connected. How to measure resistance resistance is the measure of difficulty electrons have in flowing through a particular. You can calculate resistance using this equation: resistance = voltage ÷ current resistance is measured in ohms, ω voltage (potential difference) is measured.
If we are measuring resistance of a diode, what does a high resistance in forward and reverse biased diode indicates (hint - reading in dmm is over range.

Your resistor, i take it, is actually measured with some meter again, i'll assume that your meter is perfectly accurate (it isn't, but who cares. Measuring resistance range of the ohmmeter needs to be set higher than actual resistance being measured resistance of the resistor is identified by colored.
When measuring very low resistances the problem quickly arises that every multimeter sucks in measuring very low resistancesmost multimeters 'give up' below.
